Prove whether (¬p0g)0 (r O¬s) Op) and –ro-pare logically equivalent or not. To fill the blank spaces, consider the following table: V 1 2 4 5 7 8. 9. Consider the last 5 digits of your IDs. Assume that the last 5 digits of your ID are 12075. My id last 5 digit : 14271 Now, follow the chart and select your operators sequentially. For example, for having ID 12075 the operators will be: 1 =v 2 = - 0 =A 7=- 5 =0 So you have to prove whether (¬pvq)→(r A¬s) → t) and re-p are logically equivalent or not. If a student has ID with less than 5 digits then he will put 0 at the beginning to make it 5 digits.
